UL 94 V-0.V-1.V-2 rating standards: V-0.V-1.V-2 Level Requirements: 94V-0: A。No sample should have a flame burning for more than 10 seconds after the test ___. B。For each set of 5 samples。the total time of burning with a flame after 10 ns should not exceed 50 seconds...
UL Flame Rating - UL 94 UL flame ratings group materials into categories based on their flammability. UL 94 covers two types of testing: vertical burn and horizontal burn. Horizontal Testing (HB) Procedure: A specimen is supported in a horizontal position and is tilted at 45°. A flame is...

FEATURES AND BENEFITS of UL 94 Flame Classifications UL 94-5VASurface Burn; Burning stops within 60 seconds, test specimens MAY NOT have a burn-through (no hole). This is the highest (most flame retardant) UL94 rating. UL 94-5VBSurface Burn; Burning stop within 60 seconds, test specimens...
test than 94HB. The 94-5V test is for enclosures for products that are not easily moved or are attached to a conduit system. The 94HBF and HF are used for non-structural foam materials i.e., acoustical foam. Radiant panel test is an ASTM (E162) test to determine the flame spread ...
